SPECIFICATION forming part of LettersPatent No. 596,693, dated January 4, 1898. Application filed December 16, 1896. Serial No. 615,879. (No model.)

To a/ZZ whom it may concern:

Beit known that I, DANIEL W. COLE, a citizen of the United States, residing at Baldwin, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to improvements in oil heating-stoves embracing a novel construction of hydrocarbon-burner and a novel form of heating-drum or stove-body, as will be hereinafter fully described and claimed.

I have illustrated my improved heatingstove in the accompanying drawings, forming a part of this specification, in which- Figure l is a perspective view of my improved stove. Fig. 2 is a vertical central sectional view through the same. Fig. 3 is an enlarged sectional elevation through the hydrocarbon-burner of the stove. Fig. 4 is a detail sectional view through the upper part of the stove drum or body, showing the arrangement of the heating-nues thereof.

Like letters of reference denote corresponding parts in all the figures of the drawings.

I will proceed to describe the improved hydrocarbon-burner shown more clearly by Fig. 3 of the drawings.

A designates the generator, and B is the retort, both of which are cast with the web C in a single piece of metal.

The generator A is in the form of a cylinder, and the retort B is likewise in the form of a cylinder, having integral heads b closing its ends. The retort B is arranged above the generator A in substantially the same vertical plane with the saine, and the retort and generator are united by the integral web C, which extends longitudinally between the retort and generator. The generator A is divided into vapor and steam compartments A A2 by a central transverse partition a', and in like manner the retort B is subdivided by the partition b into the vapor and steam chambers B' B".

On its lower side the generator A is provided with the integral bosses or enlargements d d', (indicated by dotted lines,) which extend a short distance below the cylindrical surface of the generator, and in these bosses are formed or tapped holes in which may be screwed the threaded upper ends of the supply-pipes E E', (shown by dotted lines,) which pipes convey the hydrocarbon oil and water to the respective chambers Al A2 of the generator A, said pipes E E Ileading from a suitable tank to supply water and oil to the pipes. The enlargement of the generator by the bosses d d imparts greater strength to the generator at the places where the supply-pipes are connected to the retort, and the joint thus secured eifectually prevents the leakage of the vaporized fuel and steam from the generator.

I prefer to connect the water and oil pipes E Eby leading them through the ends or heads of the chambers A Af of the generator, and these pipes are extended into the chambers A A2 nearly or wholly throughout the length thereof. The inner ends c c of these supply-pipes are perforated, as shown by Fig. 3, or provided with a screen which serves to retain any sediment that may be contained in the oil or water, and which causes the oil to be supplied slowly, by drops, to insure the thorough vaporization of the liquid, said pipes also affording an increased heating-surface within the generator.

The vapor and steam from the chambers of the generator A pass into the retort-chambers by means of vertical slots or passages F F',

which are formed in the connecting-web O at the time the retort and generator are cast.

On the upper side of the retort B are cast the integral bosses g g', similar to the bosses cl d', that may be cast on the generator, and in these bosses gl g are tapped holes, into which are screwed the threaded upper ends of the vapor and steam pipes H I, which are in communication with the chambers BB of the retort B. These pipes H I are curved or provided with elbows h h, and they pass alongside of the retort and generator and extend for some distance below the retort. lower ends of these vapor and steam pipes H I are provided with the elbows 'L' i', which are curved inwardly toward each other and upwardly toward the retort, and the free ends of these elbows e' i' are provided with the jets The IOO

or tips J J. The jet or tip J of the steampipe E terminates below and at one side of the tip J on the vapor-pipe E', and these tips are arranged to discharge into the mixing chamber or hood K, which is fastened to the elbow t' t" by wires or other suitable fastening contrivance, the hood 'K being provided with a transverse flame-slot at its upper end, whereby the steam and vapor discharged from the pipes into the hood are commingled therein to produce a gas, which issues from the slot in the hood and is consumed below the retort and generator to heat the same.

The pipes H I are provided withv the conf trolling-valves L, of any suitable construction, for regulating the flow of vapor and steam from the retort to the tips that discharge to the mixing hood or chamber.

During the process of casting the retort and generator I form therein vent holes or apertures m mi, which prevent blowing of the casting, and these vent-apertures are provided with screw threads to receive the threaded plugs M M, which are each made of a solid piece and threaded to screw into the vent-apertures m, whereby the retort or generator can be cleansed by detaching the plugs M.

To secure uniformity in the distribution of the heat, the burner is inclosed within a suitable casing N, (shown in Fig. 2,) which is constructed to permit ofready access to the valves and to enable it to be removed when it is desired to inspect or clean the burner, the casing N being provided with a transverse slot n at its upper end through which the flame issues and by which it is spread into a fan-like sheet.

In operation the oil and water are supplied by the pipes E E to the chambers of the generator A, in the separate chambers A A2 of which the oil is vaporized and the water converted into steam, and the steam and vapor are then passed through the slots or passages F FY to the retort-chambers B B, in which the vapors are superheated by the highlyheated retort. The vapor and steam thus produced pass into the vapor and steam pipes II I, which conduct the same to the jets or tips J J', and owing to the arrangement of the steam -jet J below and at one side of the vapor-jet J the steam impinges against the vapor as they enter the mixing-chamber K, thus commingling the vapor and steam thoroughly in the hood and producing a gas. The gas issues through the slot in the hood K and is ignited below the retort and generator, and the iiame from the hood passes up and around the retort and generator to heat the same and issues through the slot n in the casing N from which slot n the like sheet.

The hydrocarbon-burner is mounted in a base M,which has the usual feet m,the guardrailv m, and a iianged seat m", to which is fitted the stove drum or body N', the latter being easily removed by simply lifting it oft n iiame issues in a fanthe base. The drum or body N may be made of sheet metal or other appropriate material, and it is provided with a door n and with an observation-window n. The head n" of this drum is arched or crowned, and it is provided with a socket or seat 0, in which is fitted the supply-tank O, a suitable packing O', of asbestos or other heat-resisting medium, being provided around the tank to prevent the vaporization of the liquids contained in the tank by the heat of the stove. Said tank I is divided by a transverse partition into two compartments to contain the liquid hydrocarbon and the water to be supplied to the vaporizer, and with said compartments are connected the pipes E E, leading to the vaporizer.

The stove drum or body N is constructed with the heat-fines arranged in pairs at Q Q. (Indicated in Fig. 4.) Any desired number ot' pairs of these fines may be provided for the drum-as, for example, I may use two pairs arranged on opposite sides of the drum or four pairs arranged equidistant around the drum. The iiue Q of each pair is attached on the inside of the drum, and it is closed at its lower end and open at the upper end. The outside flue Q of the pair is attached to the drum opposite to the inside flue Q, and said outside flue is closed at its upper end and open at the lower end. In the drum N', near the upper closed end of the outside flue Q', is provided a port or opening R for the passage of the hot air to the ilue Q', which conducts the same downward and discharges the hot air toward the iioor of the room. Another port R is provided in the drum N at a point near the closed lower end of the inside tlue Q. These flues provide conduits for the air to discharge the same toward the floor of the room.

I also provide the stove with an external illuminating tip or burner S,whichis attached to a pipe s, leading to the retort of the hydrocarbon-burner, said pipe s being shown by dotted lines in Fig. 2 and containing a packing of wire-gauze to keep back the pressure of gas to the flame burning at the tip S. A suitable valve is provided in the pipe s to regulate the flow of gas.

In my invention the retort A A vaporizes the oil and water very quickly, and the vapor and steam pass into the superheating-chambers B B', by which they are superheated before they commingle together. The pipes E E conduct the superheated vapor and steam downward and discharge the same in streams through the jets J J and as the superheater and the pipes become very hot the vapor and steam emerge in a dry and heated condition. The stove-body being heated and confining, in a measure, a bodyof highly-heated air, the heat practically consumes all the odor, soot, and smoke passing through the stove. The

air passes through the base up to the generator or hydrocarbon-burner, and the air is heated by said generator, by the drum, and by commingling with the heated air in the drum orbody,and the drum or body radiates the heat IOO IIO

and also discharges the heated air through the ues Q Q' toward the floor of the room.

Having thus fully described my invention,

whatI claim as new, and desire to secure by Letters Patent, is-

l. The generator A and retort B situated one above the other and joined together by the integral web C, all cast in a single piece; said retort B divided by the partition b' into non-communicative chambers B, B', and the generator A likewise divided by partition a into non-communicative chambers A, A; said chambers A', B' and the chambers A2, B" being connected by the passages F, F respec-v tively produced in the web O, in combination with thefeed-pipes E, E provided with perforated elbows c e which are arranged within the chambers A', A2 of the generator, and the pipes H, I, coupled to the chambers B', B, of the retort, substantially as described.

2. A hydrocarbon-burner comprising an inclosing casing, the generator situated therein and having the non-communicative steam and vided with a transverse slot, n, in its crown,

substantially as and for -the purposes described.

In testimony whereof I aiiix my signature in presence oftwo witnesses.
